Each of the premises has one term in common with the conclusion: in a major premise, this is the major term (i.e., the predicate of the conclusion); in a minor premise, this is the minor term (i.e., the subject of the conclusion). For example: Major premise: All humans are mortal. Minor premise: All Greeks are humans.

B is the common term between the two premises (the middle term) but is never distributed, so this syllogism is invalid. B would be distributed by introducing a premise which states either All B is Z, or No B is Z. Also, a related rule of logic is that anything distributed in the conclusion must be distributed in at least one premise. All Z is B
